If you want to spawn a fuse closer or further away from the fuse box when inputting a fuse, you can use the spawnOffset which is a private variable in-case you need it.
Just make this visible in the inspector and adjust the Z axis in the Vector3. I'll also leave an example below:
/*Serialize this field if you wish to spawn a fuse with an offset further
away from the spawn point*/
private Vector3 spawnOffset = new Vector3(0, 0, 0f);
[SerializeField] private Vector3 spawnOffset = new Vector3(0, 0, VALUE-HERE);
Rotation Spawning:
You can use the FuseRotation field to set the rotation of each spawned fuse (If this is needed for your game)
